Abstract
CaZrO3:5%molEu3+ and CaZrO3:5%molEu3+/5mol%A+ (A = Li, Na, K) phosphors were synthesized by a solid state reaction. Effects of codoped alkali ions on luminescent properties of CaZrO3:5%molEu3+ was investigated. The XRD and FTIR measurements show that the all of synthesized phosphors have the same phase with pure CaZrO3. The excitation and emission spectra indicate that the codoped alkali ions enhance the Eu3+ emission intensity significantly. Moreover, the decay lifetime is also prolonged by the addition of alkali ions. The enhancements of luminescent properties for CaZrO3:5%molEu3+ can be attributed to the charge compensation and decrease of Ca2+ vacancies induced by the addition of alkali ions.
